I created a blank project in Unreal 5.3.2
In order to do so, I unselected every option on project creation screen and created a blank project as shown below.

I’ve created an “Installed Build” of Unreal Engine 5.4 following the steps here:
https://dev.epicgames.com/documentation/en-us/unreal-engine/using-an-installed-build-of-unreal-engine

I have tried to delete the .vs , Binaries , Intermediate , Saved , .vsconfig , and .sln and then clicked generate and then opened the .sln with Jetbrains Rider to build the project but it still shows me that the built failed. I also tried to directly click into the project with Unreal Engine 5.41 but it seems like it just couldn’t open. It just kept giving me those error messages telling me to build from source. And then, I tried to find out the error by building the project from the compiler to see where’s the errors. I did solve some error that I accidentally made BUT there is an error/warning that I do not understand what it means at all.

enter image description here”Hello, I’m using Unreal Engine 5.3.2 and trying to upgrade my project to Unreal Engine source code, but I’m encountering the error shown in the screenshot. When I create an empty project, meaning without any plugins, I can upgrade the project to Unreal Engine source code without any issues. However, when I include the PlayFab plugin in my project, I get this error. I’ve searched for this error on Google but haven’t found any results. Is there anyone who can help?”

I came across a problem with Unreal Engine 5.4.1, when launching a project the whole application starts to slow down a lot (freezes every second). At the same time the processor and video card are loaded by 3-4%. Tried to update drivers did not help. Also changed DirectX from 12 to 11, and also without success. Windows version 22H2.

Has anyone figured out where in source code widgets are removed when changing levels by calling ServerTravel, to remove that line/those lines in Unreal Engine 5.3.X / 5.4.X?
